Our lab broadly explores the ways in which we can better manage plant-soil-microbe relationships in organic systems in order to enhance soil fertility, with the ultimate goal of developing sustainable food production systems. A central thread that connects much of our work is the examination of winter annual legume cover crops and associated soil microbes to help maintain landscape diversity and tighten nutrient cycling. 

Our research falls within three general areas:

  • The influence of agricultural management on microbial functioning, especially as related to the legume-rhizobia symbiosis,
  • The effect of organic agriculture on soil biogeochemical cycles and processes, with an emphasis on C and N cycling,
  • The impact of soil microbial communities on agricultural productivity.

Service learning outreach

I am strongly committed to community-based learning in science education. Service-learning is an approach I use to link my classroom to local community partners working to increase access to food in marginalized Twin Cities communities.
